It's looking like hacking (multiplexed) System Memory onto this card is out of the picture for the nonce, but that WAG about translating the DuoDock's Cache implementation into a IIsi Cache Adaptation over the 030 PDS Slot has been confirmed. Props to beachycove for findingthat lil' gem. Macintosh IIci VS IIsi
Du'Oh, though! :I The IIsi L2 Cache prospect is pretty much obvious in hindsight. That's what the PDS is designed to do, get the Processor's Direct Signalling (per trag, see above) onto an expansion connector. Otherwise the PowerCache Cards wouldn't work, nor the FPU sockets.
L2 Cache SRAM ought to be right at home on the raw 68030 signals as well. Now I'm a very happy camper . . . erm . . . hacker! [

p.s. hacking L2 onto the NuBus adapter or the RCPII/IIsi Card could be another avenue of approach as well, but . . .
